“…While PM 2.5 levels have largely decreased in recent decades ( Our Nation’s Air , 2022), the contribution from biomass burning has increased in some regions across the US (Milando et al, 2016; Singh et al, 2022)Wildfires are increasingly responsible for PM 2.5 levels and contribute to biomass burning (Burke et al, 2023; Enayati Ahangar et al, 2021; Li et al, 2021; O’Dell et al, 2019). Further, human-caused climate change and wildfires have a bidirectional relationship, such that climate change is leading to more and larger fires, which release gasses and PM that amplify climate change (Boegelsack et al, 2018).…”

Exposure to outdoor particulate matter (PM2.5) represents a ubiquitous threat to human health and, in particular, the neurotoxic effects of PM2.5 from multiple sources may disrupt neurodevelopment. Studies addressing neurodevelopmental implications of PM exposure have been limited by small, geographically-limited samples and largely focus either on macroscale cortical morphology or postmortem histological staining and total PM mass. Here, we leverage residentially-assigned exposure to six, data-driven sources of PM2.5 and neuroimaging data from the longitudinal Adolescent Brain Cognitive Development Study (ABCD Study), collected from 21 different recruitment sites across the United States. To contribute an interpretable and actionable assessment of the role of air pollution in the developing brain, we identified alterations in cortical microstructure development associated with exposure to specific sources of PM2.5 using multivariate, partial least squares analyses. Specifically, average annual exposure (i.e., at ages 8-10 years) to PM2.5 from biomass burning was related to impaired neurite development across the cortex between 9 and 13 years of age.

“…The metallic elements including Al, K, Ca, Fe, and Mg are mostly originated from the crustal materials (Amato et al, 2014;Hsu et al, 2016;Fanizza et al, 2018), while Fe, Ba, Zn, Cu, and Pb come mainly from the vehicular exhaust (Jeong et al, 2019;Yang et al, 2019;Bi et al, 2020;Tseng et al, 2022). The EC in the carbonaceous content mainly comes from the incomplete combustion of biomass and fossil fuels, which strongly affects the absorption of visible light and thus promotes global warming (Dinoi et al, 2017;Wu et al, 2018;Singh et al, 2022). The OC/EC ratio has been used to determine the formation of secondary organic aerosols (SOAs) (Wu et al, 2009;Feng et al, 2007).…”

This study investigated the temporospatial variation, chemical composition, and source resolution of fine particles (PM2.5) in the southeastern seas of the Taiwan Island. 24-hr PM2.5 was sampled simultaneously at two remote sites, the Green Island (West Pacific Ocean; WPO) and the Kenting Peninsula (northern Bashi Channel; BC), in four seasons. After sampling, the chemical fingerprints of PM2.5 were characterized and further applied to resolve the potential sources of PM2.5 and their contribution by using a receptor model on the basis of chemical mass balance (CMB), enrichment factor (EF), and backward trajectory simulation. It showed that PM2.5 concentrations in winter (10.8 μg m -3 ) and spring (12.0 μg m -3 ) (i.e., during the period of Asian Northeastern Monsoons; ANMs) were higher than those in summer (4.0 μg m -3 ) and fall (6.6 μg m -3 ). In terms of chemical composition of PM2.5, secondary inorganic aerosols (SIAs = NO3 -, SO4 2-, and NH4 + ) (56.7~67.2%) were the dominant component of water-soluble ions (WSIs) in PM2.5, while crustal elements (Mg, Al, Ca, Fe, and K) (44.0~61.2%) dominated the metallic contents in PM2.5. High EF values (> 10) showed that V, Mn, Ni, Cu, and Zn were potentially contributed from anthropogenic sources. Moreover, organic carbon (OC) (0.6 μg m -3 ) was superior to elemental carbon (EC) (0.3 μg m -3 ) in PM2.5. The OC/EC ratios higher than 2.0 showed the potential chemical formation of secondary organic aerosols (SOAs) in the atmosphere in winter and spring. Trajectory simulation indicated that high PM2.5 concentrations were mostly originated from North and Central China, Japan islands, and Korea Peninsula. Major sources of PM2.5 resolved by CMB receptor modeling were ordered as: sea salts (19.9%) > fugitive dust (19.8%) > industrial boilers (oil-fired) (10.8%) > secondary sulfate (9.8%) > mobile sources (8.0%).
